KEYLESS LOCKING DEVICE.

SPEGIFIGATION forming part of Letters Patent No. 717,941, dated January 6, 1903. Application filed $eptember 16, 1895. $eria1No. 562,653. (No model.)

T0 at wk/07% it may concern:

Be it known that I, HARRY W. STANDIDGE, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented a new and useful Keyless Locking Device, of which the following is a full, true, and exact specification.

My invention relates to a novel device for locking and unlocking toy banks, cash-drawers, and such like without a'key, the object being to provide a device of this character which is simple in construction, which will be difficult to open unless it is understood, and which will not be liable to be easily gotten out of order; and it consists in the features of construction and combinations of parts hereinafter fully described and claimed.

In the drawings accompanying this application, Figure 1 is a side elevation in perspective of a toy bank made in accordance with my invention, having one side plate removed, so that the inner working parts may be more readily seen. Fig. 2 is a detail view of one of the working parts of my device.

In said drawings, H represents a drawer mounted in a box I, said box I being a separate box, as shown, or one of a series of compartments, such as one of the drawer-spaces in a bureau or such like. A projection or pin D is rigidly mounted on the outer surface I of one of the sides of said drawer near therear end thereof and is adapted, as said drawer is moved back and forth, to be engaged by a member A, which is pivotally mounted on a pivot 0 within said box I near its rear end in the path of said projection. Said member A is somewhat C-shaped, the pivot 0 being in the rear upper corner and the member being so balanced that it will normally rest'in an upright position. The upper forward arm J of said member A is bent downward and extends about half the depth of saidmember. It is provided on its inner edge with two projections F and G, thus forming two recesses K and L, whose use will be further explained later. The

lower forward arm E of said member A is bent upward and backward at an angle of about thirty degrees and extends slightly above the lower end of said arm J, a space B being left between said arms J and E to per- In the position mit said pin D to pass.

shown in Fig. 1, with the drawer partly withdrawn, the open side of said member A is presented to said pin D, and said member A hangs in the path of said pin D, and the lower end of said arm J hangs at such a height in relation to the height of said pin D that when said drawer H is pushed in said pin D will engage the lower end of said arm J, the outer lower corner of which .is rounded off, and as said pin is forced rearward it will raise said arm J, thus turning said member A on the pivot C, and will pass in under the lower end of said arm J and said projection F, when said member A on account of being balancedwill resume its normal position and said pin D will be behind said arm J and a little below said recess K. As said pin D is forced farther rearward it will come in contact with the upper slanting end of said arm E and will force said arm downward, thus swinging said member A on its pivot O in the opposite direction until said pin shall have passed over the upper end of said arm E, when said member A will resume its normal position and said pin D will project within the open space or recess M in said memberA and behind the upper hooked end of said arm E. The drawer H is now locked with said casing I, and it will be readily understood that if an attempt should be made to withdraw said drawer said pin'D will be prevented from moving forward by being engaged by said arm E; but should the forward end of said member A be depressed by any means said pin D would still engage with said arm J, entering one or the other of said recesses L or K, and thus the drawer H would still be locked.

When the device is applied to a toy bank or other smallarticle, it may be unlocked by raising the forward end of said bank or box until said pin D will pass freely over said arm E. This may be done definitely by raising the forward endsay forty five degrees-and pulling out the drawer until the pin engages with said arm J by entering said recess L, after which the bank should be brought back to a horizontal position. Now if the drawer is slowly forced rearward the pin D will be disengaged from said projection G and said member A will swing on its pivot, thus bringing the pin D in front of said arm E, but behind said arm J and nearly opposite said recess F. Now if the forward end of said bank is further depressed said member A will swing still farther on its pivot and said pin will be free to be drawn forward and the drawer will be unlocked.

When the device is applied to a cash-drawerproper time and said pin D is freed from said arm E, and a like action will free it from said arm J, the rearward end of said projection F being cut off on a forward slant for the purpose of allowing said pin when drawn forward against the rearward edge of said arm J to cause the same to be depressed, thus swinging said member A on its pivot and allowing said pin to enter said recess F. Now when said pin D is moved quickly back out of said recess F said member A will swing on its pivot, and if the pin D is quickly drawn forward again while said arm J is at the upper limit of its motion said pin can be freely drawn forward and the drawer unlocked.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

1. In adevice of the kind specified, the combination with two members movable relatively to each other, of a projection on one of said members, a plate pivotally mounted on the other of said members, in the path of said projection, and having a recess adapted to receive same, and arms on said plate at the mouth of said recess adapted toe-ngage said projection to prevent withdrawal of same from said recess, said plate being held in a given position by gravity and being free to be turned on its pivot to permit the said projection to be withdrawn from or entered into said recess.

2. In adevice of the kind specified, the combination with two members movable relatively to each other, of a projection on one of said members, a plate pivotally mounted on the other of said members, in the path of said rojection, and having a recess adapted to receive same,-and arms on said plate at the mouth of said recess having overlapping ends adapted to engage said projection to prevent withdrawal of same from said recess, said arms being provided with inclined outer edges whereby when said projection is forced against same said plate will be turned on its pivot and said projection will be permitted to pass between said overlapping ends of said arms and enter said recess, said plate being held in a given position by gravity and being free to be turned on its pivot to permit the said projection to be withdrawn from or entered into said recess.

3. In adevice of the kind specified, the combination with two members movable relatively to each other, of a projection on one of said members, a plate pivotally mounted on the other of said members, in the path of said projection, and having a recess adapted to receive same, and arms on said plate at the mouth of said recess adapted to engage said projection to prevent withdrawal of same from said recess, the outer one of said arms being provided with one or more inwardlyprojecting lugs forming one or more spaces adapted to receive said projection when an attempt is made to withdraw same from said recess, said plate being held in a given position by gravity and being free to be turned on its pivot to permit the said projection to be withdrawn from or entered into said recess.

4. In adevice of the kind specified, the combination with two members movable relatively to each other, of a projection on one of said members, a plate pivotally'mounted on the other of said members, in the path of said projection, and having a recess adapted to receive same, and arms on said plate at the mouth of said recess adapted to engage said projection to prevent Withdrawal of same from said recess, the inner one of said arms being inclined inwardly, thus forming a hook adapted to receive said projection when an attempt is made to withdraw same from said recess, said plate being held in a given position by gravity and being free to be turned on its pivot to permit the said projection to be withdrawn from or entered into said recess.

In testimony whereof I affix my signature in presence of two witnesses.

HARRY W. STANDIDGE.
